Reports according to Abo Abdo Sajjo, the leader of Northern Storm, the FSA have just accused Nusra of being allied with ISIS in justifying raids which have taken over all Nusra HQs just about now in Northern Aleppo, arresting reportedly tens of Nusra fighters specifically in the Azaz area where Northern Storm (component of Jabha Shamieh coalition) controls. Jabha Shamieh is responsible for these reported raids. Nusra has in some others reports around 50 or less fighters in the Azaz pocket.
